文摘

The redox-neutral direct coupling of arylphosphine oxides with heterobicyclic alkenes proceeds smoothly under rhodium(III) catalysis involving hydroarylation followed by dehydrative aromatization to form biarylphosphine oxides. Related phenylphosphinic and phenylphosphonic esters as well as phenylphosphine sulfides also undergo ortho-arylative coupling. Furthermore, phenylphosphinothioic amides can be transformed to fused dibenzophosphole derivatives through rhodium-catalyzed coupling with heterobicyclic alkenes and successive intramolecular phospha-Friedel鈥揅rafts reaction in a one-pot manner.
